A spectral integral method (SIM) is developed to solve the scattering problem from smooth multilayered bodies of revolution (BoRs). This SIM is a spectral method to improve the accuracy and efficiency of the SIM by the fast Fourier transform (FFT) algorithm. This method can achieve high accuracy and greatly reduce the computational time consumption. In our BoR-SIM, the BoR generatrix current is expanded...
In this paper, the distance between source and field points is divided into ultra-near field region, near field region and far field region for fast and accurately calculating the spatial Green's function. The spatial Green's functions within the three regions are respectively calculated by the Langrage interpolation scheme, the DCIM with surface wave poles being extracted and the SDP with leaky wave...
Expressing the traveling wave phase dependency, the use of PE bases is able to reduce the number of unknowns dramatically, and lead to the sparsification of the impedance matrix, which will be reported in our other paper. Secondly, the PE bases cause better condition number and faster convergence rate in iteration solution because of showing intrinsic property of the induced current. Thirdly, the...
